How hard do you want to run them? You can go up to 100 watts if you get those big ass splayed pin sinks. Last I seen you had to get them from China though. If you go rapid led 140mm pin sinks I think you can go 4 vero 29c per hlg-320h-c1050a.

Okay so (3)hlg-320h-c1050a about $90 each and (12) vero29c-is there a universal part #?
and some heat sinks $20 each
This sound right?
âŚIâm thinking maybe 2 instead of 3 for now

Looks about right.
Ya it definitely wonât be cheap. If youâre not working with a major discount code or anything, you could even do one now. The heatsinks run about $20 and youâll need 1 per cob.
Do you want the 2700k specifically?

I thought it would be best for flower but Iâm flexible
Donât know whatâs up with the 10k Flux indicator?
If these are so much more expensive are they better than the lights I have? Or would it be best to build the same one?
Iâm out. Talk to ya tomorrow
Sorry, trying to kids to bed at same time. Where it says 10k in example, that would be a nominal reference to luminous of flux of said led. In this case, thatâs the identifying part of part number that says itâs a 29mm cob, or the vero 29. The vero 18 thatâs same color temp, cri, and so on will have a 400 there I think. Which signifies itâs a 4000 lumen cob.
However, not every vero 29 will have flux of 10,000 lumens. Some may be lower and others will be higher. Luminous flux varies a lot based on light spectrum because of how itâs measured. Itâs one of the main reasons luminous flux not as important in horticulture lighting. Itâs completely possible for an led with a lower luminous flux to have a higher photosynthetic photon flux.
Iâm not exactly sure who has the lowest price on the vero 29 right now. But you can usually build cobs for around $1 per watt too. You figure per 4 cobs itâs $90 driver, $80 in heatsinks, and $100 in 4 cobs. You score a 10% code and youâre at about $250 for that stuff. Another $50-$70 for aluminum, connectors, wire, and thermal compound and youâre in the neighborhood of $300 for about 300ish watt light.
A lot of times the best deal lies in who has what in stock, and/or who pops a good discount code. Arrow ran 30% off over the summer, by that a $1000 build is now $700. Pretty rare though.
Not sure how pricing would work out on using some of the double row Samsung f series, but arrow had them priced well. The 1120mm version is like a 100 watt strip. You need an $18 piece of heatsink to go with them. Hlg-320 will run 3 of them. Iâm guessing still about $1 per watt

I went with the same light
Arrow bill for 26 bxeb and 2 hlg-185h-c700a was 338.54 after 15%off coupon and plus $50 tariff,
thanks Trump
So itâs about the same 400w for $400

You shorted yourself 2 strips, I think. And still have cost of aluminum, wiring, connectors, and tape right? All things considered they usually work out to be reasonably close if youâre careful purchasing. Glad you got a discount code too!

Days from flip
Left 44
Right 65
Closet 38
New light supplies should be here tuesday Right looks done with the naked eye. Itâs all yellowed out and all the pistils are amber except for a few foxtails. Left is getting fatter by the day.
I pulled all the ladies from the closet and trimmed em up pretty good. I didnât take all the fans but I got most of the big ones. Still canât tell 
BEFORE
AFTER
Hoping to harvest the right, set the new light up, and move the closet girls to the flower room within a week. Then I can use the closet to veg my 2 bagseed indicas.
Trichs from yesterday. Need to hurry. Got some Bud Candy coming tomorrow
Just waiting on an email invite for the lab and Iâll be joining some of you over there. Yay!
Until I think of something else
